Ya I'm thinning at the top. Been doing so for the past few years. I had my hair at a medium length which just accentuated the thinning at the back so I got a buzz cut; a number 4 at the top and 2 at the sides/back and it looks great. Short is definitely the way to go, especially if you're thinning evenly like me. I have my facial hair at a similar length and I look legit. Should've done it earlier. The more it thins the shorter you should go.
